On April 22nd, Nintendo issued a Digital Millennium Copyright Act (DMCA) takedown for the port, resulting in its removal from several hosting sites, such as the Vancouver, Washington-based PXC Commodore Club.

Good times. Due to a DMCA takedown notice we had to remove the Super Mario Bros 64 download from our website blog post from 4 days ago. Hopefully everyone enjoys the #Commodore 64 #C64 game who was able to snag it.

The port is particularly noteworthy because the Commodore 64 only has a clock speed of around 1Mhz — roughly 55 percent of the NES’ speed. Therefore, the Commodore 64 is not a system that is designed to run the smooth full-screen scrolling found in titles like Super Mario Bros.

Nintendo has yet to publicly comment on the matter. However, the company has traditionally been strict about fan projects involving its intellectual property (IP).

Outside of a seeming desire to closely protect its IP, Nintendo has also been pushing retro gaming in its own ways, so it likely sees these fan efforts as a form of competition.

In addition to its NES Classic and SNES Classic mini consoles, which come pre-installed with beloved old-school titles like Super Mario Bros., Nintendo has been using retro games as a selling point for its Switch Online service. Those with a paying subscription to Switch Online are able to access a growing catalogue of digital NES games, Super Mario Bros. included.
